2016-07-07drm/amdgpu: some improvement in parsing inputsEric Huang1-3/+9
It changes the way to skip newline character and also avoids warning message from some compiler. Reviewed-by: Alex Deucher <[email protected]> Signed-off-by: Eric Huang <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2016-07-07drm/amdgpu: add the common code to support mclk ODEric Huang1-0/+55
This implements mclk OverDrive(OD) through sysfs. The new entry pp_mclk_od is read/write. The value of input/output is an integer of the overclocking percentage.

2016-07-07drm/amdgpu: add the new common pm code to select the clock levelsEric Huang1-18/+32

2016-07-07drm/amdgpu: add powerplay sclk OD support through sysfs (v2)Eric Huang1-0/+49
Add a new sysfs entry pp_sclk_od to support sclk overdrive(OD) overclocking, the entry is read/write, the value of input/output is an integer which is the over percentage of the highest sclk. v2: drop extra semicolon Reviewed-by: Alex Deucher <[email protected]> Signed-off-by: Eric Huang <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2016-06-17drm/amdgpu: missing bounds check in amdgpu_set_pp_force_state()Dan Carpenter1-15/+13
There is no limit on high "idx" can go. It should be less than ARRAY_SIZE(data.states) which is 16. The "data" variable wasn't declared in that scope so I shifted the code around a bit to make it work. Also I made "idx" unsigned.

2016-03-02drm/amdgpu/pm: update current crtc info after setting the powerstateAlex Deucher1-3/+3
On CI, we need to see if the number of crtcs changes to determine whether or not we need to upload the mclk table again. In practice we don't currently upload the mclk table again after the initial load. The only reason you would would be to add new states, e.g., for arbitrary mclk setting which is not currently supported.

2016-02-22drm/amdgpu/pm: adjust display configuration after powerstateAlex Deucher1-2/+3
set_power_state defaults to no displays, so we need to update the display configuration after setting up the powerstate on the first call. In most cases this is not an issue since ends up getting called multiple times at any given modeset and the proper order is achieved in the display changed handling at the top of the function.

2016-02-10drm/amd/powerplay: add some sysfs interfaces for powerplay.Eric Huang1-1/+335
The new sysfs interfaces: pp_num_states: Read-only, return the number of all pp states, 0 if powerplay is not available. pp_cur_state: Read-only, return the index number of current pp state. pp_force_state: Read-write, to write a power state index will switch to selected state forcedly and enable forced state mode, disable forced state mode. such as "echo >...". pp_table: Read-write, binary output, to be used to read or write the dpm table, the maximum file size is 4KB of page size. pp_dpm_sclk: Read-write, reading will return a dpm levels list, to write an index number will force powerplay to set the corresponding dpm level. pp_dpm_mclk: same as sclk. pp_dpm_pcie: same as sclk. And add new setting "manual" to the existing interface power_dpm_force_performance_level.

2015-10-19drm/amdgpu/dpm: don't add pwm attributes if DPM is disabledAlex Deucher1-2/+6
PWM fan control is only available with DPM. There is no non-DPM support on amdgpu, so we should never get a crash here because the sysfs nodes would never be created in the first place. Add the check just in case to be on the safe side. Signed-off-by: Alex Deucher <[email protected]>
2015-08-17drm/amdgpu: don't grab dev->struct_mutex in pm functionsDaniel Vetter1-2/+0
Similar to radeon, except that amdgpu doesn't even use struct_mutex to protect anything like the shared z buffer (sane gpu architecture, yay!). And the code already grabs the globa adev->ring_lock, so this code can't race with itself. Which makes struct_mutex completely redundnant. Remove it.
